PlCKER-CHECKING MEANS FOR LOOMS.

SPECIFICATION forming part Of Letters Patent No. 729,048, dated May 26,1903.

Application filed October 17. 1902. Serial No. 127.670. (No model.)

If 0 all whom it may concern.-

Be it known that I, ARTHUR EAVES, a citizen of the United States, and aresident of Fall River, county of Bristol, State of Massachusetts, haveinvented an Improvement in Picker-Checking Means for Looms, of which thefollowing description, in connection with the accompanying drawings, isa specification,1ike characters on the drawings representing like parts.

This invention relates more particularly to picker-checking means forlooms; and it has for its object the production of novel and simplemeans for very efiectively checking the outward movement of the pickerwhen the shuttle enters the shuttle-box.

The various novel features of my invention will be fully describedhereinafter and particularly pointed out in the following claims.

Figure l is a front elevation of one end of the lay of aloom and theshuttle-box thereon with one embodiment of my invention applied thereto.Fig. 2 is a top or plan view of the mechanism shown in Fig. 1. Fig. 3 isa top or plan view of the shuttle-binder detached to more clearly showthe picker-check carried thereby, and Fig. 4. is a rear elevation of thebinder and picker-check.

The lay A having a shuttle-box thereon comprising a front plate I), backplate or wall I), shuttle-guard or top plate 11 the binder B ,pivotallymounted near its outer end upon the lay at b the spring-controlledprotectorshaft 1), and the upturned finger 19, carried thereby andbearing against the free inner end of the binder, may be and are all ofusual or well-known construction and operate in the usual manner. Thelay is shown as longitudinally slotted at A Fig. 2, for the staff of theusual picker P.

As shown in Fig. 2, the swell 2 of the binder extends into the path ofthe shuttle when the latter is not in the box, and the impact of theentering shuttle throws or swings the free end of the binder out againstthe usual spring, (not shown,) the greater the impact of the shuttleupon the binder the greater the outward movement of the latter. Inaccordance with the illustrated embodiment of my present invention thisshuttle-induced movement of the binder is made efiective to actuate apickercheck and thereth'rough check the outward throw of the picker,thus preventing rebound of the shuttle in the box.

The picker-check is shown as an elongated hook-like memberoo, the side0' thereof being bent at o c and secured to the back face of the binderby suitable means, as screws 5, Fig. 4, so that the side 0 extendslongitudinally parallel to and preferably just within the path ofmovement of the outer side of the picker P, so that there will befrictional engagement therebetween.

I prefer to make the check resilient, and it is conveniently made of ametal strap of requisite size and stiffness, the inner end of the side 0of the check being bent out or flared, as at 0 I As shown clearly inFigs. 1 and 2, the member c 0 extends beyond the outer pivoted end ofthe binder to afford ample room for the movement of the picker andpresents a horizontal U-shaped hook, into which the picker enters on itsoutward throw, the distance between the sides a 0 being great enough topreventthe side 0 from engaging the rear face or side of the picker.When the incoming shuttle strikes the swell 2 of the binder, the latteris thrown outward,swinging on its fulcrum b and the checking member ismoved thereby, so as to project the side 0 thereof a greater or lessdistance inward within the path of the front side or face of the picker,the flared inner end 0 of the check. member 0 first engaging the pickeron its outward stroke. The pressure thus exerted upon the picker byengagement with the check acts to frictionally retard and check thepicker, so that it will gradually slow down as it reaches the end of itsoutward stroke, the resiliency of the check permitting it to flex as thepicker moves along.

It will be obvious that the greater the impact of the entering shuttleupon the binder the greater will be the quick outward throw of thelatter, and consequently the greater will be the pressure exerted uponthe picker by my novel picker-check, the pressure or retarding actionexerted thereby thus being proportional to the speed of theincomingshuttle.

By engaging only one side of the picker IOO there is no Wedging actionupon it, and it is the more readily and quickly freed when the shuttleis thrown from the shuttle-box.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a loom, the lay having a shuttle-box, a binder, a picker, and anelongated hooklike friction check mounted on the binder, shuttle-inducedmovementof the binder caus ing the check to engage the picker with apressure proportional to the force with which the incoming shuttlestrikes the binder.

2. In a 100m, the lay having ashuttle-box, a binder, a picker, and anelongated, resilient checking member fixedly mounted upon the binder andlongitudinally extended adjacent and substantially parallel to the pathof movement of the picker, said checking member being brought intooperative engage- ARTHUR EAVES.
